The components of rRNA consist of phosphates and amino acids compiled into one strand.
physical description:
The ribosomal RNAs form two subunits, the large subunit (LSU) and small subunit (SSU).
A ribosome also has 3 binding sites called A, P, and E. Small Subunit
Where it is formed: Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.
Where it is found: rRNA is found mainly in the cytoplasm of the cell, however they can also be found on the endoplasmic reticulum.
Job of rRNA: rRNA are the protein builders of the cell. They connect amino acids to build long chains, and those are known as proteins.

How the molecule works: The rRNA provides a technique for decoding mRNA into Amino Acids and that is how the rRNA synthesizes proteins in living cells during translation.
